Raymac, you cannot make dyesub decals, it will not work. You need a solid ribbon thermal transfer printer such as the Alps 5000 or the Oki DP5000 in order to make decent decals. I have bought an Alps 5000 a while back, and put down quite some money for it. Figure $500 up for something that's not total trash (nr. 1 reason for sale on ebay...)....
Also the ribbons run quite expensive (between $5 and $10 per color, 5-8 colors per set, about 30 pages per ribbonset)....so unless you are printing an awful lot of decals, this investment won't be worth it.
(Oh jes...jpg files won't really come out on these...you need a good corel vector image for thermal transfer decals...a lot of work because you will hardly get your hands on them and need to draw them all up yourself).

The cheapest way to these types of decals is to draw them up in corel, and get the file to someone who already owns one of these. Many printshops have them, also quite often small companies doing t-shirts. Listren around, and then have them print up your finished files. That way you will not have the trouble and expenses of the printer....and if they charge you between $15 and $20 per US Letter page, you'll be off really well and probably will never come out as expensive as when buying (even a used) printer.
If you want i can also print them for you, i only charge material price.

Hope this helps
best regards
Hank
